Noise cancellation is very much the tech expression of today – at least in the audio world. Every headphone producer seems to be speaking about Active Noise Cancellation (ANC), which pleases us greatly at Jabra because we have a long history of engineering such sound solutions.

We started developing ANC two decades ago, and have today enhanced and improved this technology along with the digital signal processing (implemented via a two-microphone solution) now found in the Jabra Evolve 75.

But what is noise cancellation? How does it work, and how can it help you work? The first thing to note is that there are two types of cancellation – passive and active – and both are important features of the Evolve 75. Continue reading →

If you’ve ever shopped for headsets or headphones, I bet you’ve heard the term “noise cancellation” used once or twice. I can also bet that you weren’t always quite sure what it meant. It’s not your fault: Depending on the context, noise cancellation can mean a number of things, and companies aren’t exactly consistent in how they use the term. Let’s try to unravel the riddle.

First off, there are two broad types of noise cancellation – one in the microphone(s) and one in the headphones themselves. The first type helps the person on the other end of the line to hear your voice instead of the ruckus in the bar you’re calling from. The second type protects you – the wearer – so that you aren’t disturbed by that same bar noise.

You know that sound you hear when you walk onto a busy trade show floor? That loud, intense human buzzing? When you enter a busy contact center, you can hear the same thing. The difference is that when someone calls into that contact center, they don’t want to hear a trade show in the background. Enter noise-cancelling headsets.

Let’s look at how this tech actually works, especially when it comes to noise-cancelling microphones. Continue reading →
